Application filed December 4,1905. Serial No. 290.172.

Be it known that I, EDWARD F. KUNATH, a citizen 'of'the .United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following .is a specification. r

This invention relates to the line-spacing or'paper-feeding devices of type-writing inachines, particularly those of the front-strike and esp'eciall y those in which it is desired to insert each bill or sheet in the machine once for every line of writing written thereon and also where'it is desired to make carbon-or other copies ofithe successive totals of many bills upon a single tally-strip.

I mount over the dplaten in such a manner as to be ca able of a iustment both alon the platen an also forwardly and rearwardly a late or tablet provided with gages for the eading' and side edges of the paper, whereby when the usual pressure-rolls are released or cast oil:' a sheet or set of sheets may be introduced around'the platen and adjusted upon said tablet to said gages so that the first item and all succeeding items written thereon shall appear in lalinement upon the written bill even though the latter is withdrawn after the writing of each item and reinserted to write the next item; By having the gages adjustable it becomes practicable to have the 7 writing fall at any particular point desired on the sheet-as, for instance, on a ruled line or between ruled columns.

pieceof paper of the totals of a large number.

of bills, I carry a tally-strip or paper ribbon from a coil and rewinding it on a spool,

p an I also provide means to be used when "aaline by linea' desired for making carbon-records upon the tally-strip.

In order to draw the paper ribbon-from the coil, I provide either one or a pair or pressurerolls to press the same against the platen. By this means the rotation effects the line feeding of the paper ribbon. The latter is to be line-fed only once for eachtotal written thereon, and-hence has to'remain stationary duiingthe rotation of the platen, as the bill is To this end I provide Fig. 7 is the roller-releasing rod as shifted endwise, so

"the platen, while the. auxiliar shown in full lines as cast 0 means for releasing the roll or rolls that press the paper ribbon'against the platen, whereby the ribbon is caused to remain motionless during the rotation of the platen. I further contrive to move the main pressure-rolls and the auxiliary pressure-rolls alternately into and out of'use, so that by depressing a single release-key the main pressure-rolls are cast off and the auxiliaryrolls are brought into action, whereby the paper ribbon may be first fed in line and then the bill withdrawn and a new bill inserted and adjusted by means of the to tablet and gages. Thereupon the'release-key may be restored to normal position, thereby releasing the auxiliary with the platen, and at the same time restoring the. main rolls totheir active positions, thereby to feed the inserted bill. I further provide means whereby when desired the afixilia rolls'may be both released and 'estoredsimultaneously with the main rolls by means of the same're ease-key.

after a pear. Int e accompanying drawings, Figure 1 is a front elevatlon of a wide carriage of an Underwood front-stnke writing-machine,

showing. the main pressure-rolls as running upon the platen, while the auxiliary rolls are cast ofi'. Fig. 2 is a view of a rock-shaft formed with cams to release the several pressure-rolls, saidshaft having two sets of cams for this purpose and being movable endwise, so as to bring either set into play. Fig. 3 is u I a lap of the main and auxiliary pressure- In order to keep a tally-record upon one ro s and. a purtenances. Fig. 4 is a rear elevation oi the tablet and gages mounted. above the platen. Fig. 5 is a vertical section of the same, taken from front to rear. Figs. 4 and 5 illustrate the adjustability of said tablet. Fig. 6 is a perspective rear view which illustrates the action of the main and auxiliary pressure-rolls in unison, all of said rolls being shown in full lines in workin positions and being also shown in dotted lines as cast off simultaneously by the release-key. a view similar to Fig. 6, but showing as to bring the, other set of releasing oams into play. At this fi re the main pressurerolls are shown info. lines as running upon roll or rolls is The-dotted rolls, so that the paper-ribbon will not feed Other objects and advantages will hereinmain pressure-rolls are cast off, a sheet or manipulation of the lines show the operation of the release-key which cast-off the main.rolls and simultaneously brings the auxiliary rolls into play. ig. S is an end elevation illustrating particularly the means for carrying and 'eeding a coil of paper ribbon. Fig. 9 illustrates the method of employing a roll of carbon-ribbon in connection with the paper ribbon or tallystrlp.

Type-bars 1 strike upon the front side of a platen 2, which is mounted on an axle 3 in a platen-frame comprising a paper-shelf 4 and ends 56, the platen being provided with the usual line-spacing mechanism, including a ratchet-wheel 7.

Bills or other sheets are introduced between the paper-shelf 4 and the platen and guided forwardly around the same by a deflector 8. Rear rolls 9 and front rolls 10 press the sheets against the platen, said rolls carried upon axles 11 12, which are pressed toward the platen by arms 13 14, upon which bear springs 15 16, thelatter secured upon a fixed rod 17 of the platen-frame and said rod serving also as a pivot for said arms. These main pressure-rolls are released by means of a key 18, fixed upon a lever 19, which is pivoted at 20 upon the platen-frame and has an arm 21, which is connected by rock-shaft 24, which effects the releasing of said pressure-rolls. Said rock-shaft has depressions or cutaways in its opposite sides to receivearms 26 27, formed upon said pressure-arms 13 14, the construction being such that when the shaft is rocked through about ninety degrees said arms 26 and 27 are separated from each other and the arms 1 14 moved away from the platen, thereby releasing the pressure-rolls. At this time the arms '26 27 rest upon the uncut periphery of the rock-shaft, as at Fig. 2, and are thereby mechanically held away from the laten, so that the operator may have both ands free for paper. When these sheets may be introduced at the rear of the platen and pushed around beneath and up in front of the same, and its leading portion may be pressed down upon a tablet 28 and the leading edge of the paper adjusted to a age 29, formed along the rear edge of said t-ahlet, while the side justed to a gage 30, formed hand edge of said tablet, lease-key 18 tion, thus bringing the main pressure-rolls into-action, whereupon the sheet or sheets may be fed line byline in the usual manner. The provision of the said gages makes it practicable to bring successive items on the same sheet into accurate alinement', even though the sheet is withdrawn after writing each-line and reinserted forwriting the succeeding line, as is sometimes necalong the rig'ht-- whereupon the rea link 22 to a crank-arm 23, the latter mounted upon-a .coil downwardly and toward the platen by arms'55 56 edge of the paper may be admay be restored to normal posi-- essary in making out bills. Said, tablet is secured upon arms 31 and 32, which fit upon a horizontal fixed rod 33, extending from end. to end of the platen-frame. In the under side of the rod is formed a groove 34 to receive cylindrical loose splines or keys 35, which are pressed into said groove by springs 36, the latter-secured to brackets 37, fastened to said arms and engaging said rod 33. The tablet, together with the arms, may be slid along said rod, and hence adjusted to any point required along the platen, so as to enable the writing to fall at any desired point or points on the sheet, as between ruled columns, while the springs 36 hold the tablet and gages tightly wherever adjusted. Gages 38 extend backwardly and downwardly from said arms 31 32 and toward the papershelf 4, Fig; 8, thereby to guide the operator in introducing the sheets. Said arm 31 has a forward extension 39, Fig.8, having a slot 40 extending from front to rear, and a screw 41, passing throu h said slot and threaded into the gage or le ge 30, secures the latter to the arm and permits forward and backward adjustment of the gage and tablet. The arm 32 is also provided with a forward extension 42, Fig. 5, having a slot 43, through I which passes a fastening-screw 44, so that either one or both ends of the tablet may be adjusted either forwardlyor backwardly, so

as to enable the writing to fall upon ruled I lines on the bill or at any desired point on the aper. The gage 30 is preferably at the rightliand end of the .tablet, and the left-hand end 'of the latter preferably overlies the slotted extension 42, Figs. 1 and 4. Access to the screw 44 is afforded by tipping the. tablet up on the rod 33.

A coil of paper ribbon 45 is carried upon a core or axle 46, mounted in a pair of arms 47, erected upon a bracket 48, which is secured by a screw 49 to the right-hand end 6 of the platen-frame. The rib around beneath the platen and up in front is wound upon a spool 51, whose axle 52 is also journaled in said arms 47. The paper ribbon is pressed against the platen byrear and front rolls 53 and 54, which are pressed and springs 57 53, said arms pivoted upon the rod 17. Springs 59, one'at each end of the axle 46, press the coil 45 up against the s 001 51, so that when the. ribbon is drawn 0% 53 and 54 with the platen 2 the hon is wound up by the spool caused to rotate by reason of the tween it and the coil 45.

Each slot 60 is opened at its bottom to permit detachment of the coil, and an openslot 61 is provided to receive the axle o cesses 68, which agree in pos1t1on wlth re- 52 of the winding-spool, so as to permit de- As seen at Fig. 7,

tachment of the latter. the auxiliary rolls 53 54 for feeding the paper ribbon are cast ofi during. the line-feeding of .the bill by means of the main pressure-rolls,

; so as to permit the paper ribbon to remain stationary. At the completion of the billor itemthereon the total is written u on the' paper ribbon or tally-strip 50, and t en the.

release-key 1 8 is depressed, thereby casting off the main pressure-rolls, as seen in dotted lines at. Fig.7, and bringing the auxiliary rolls against-the platen, so that by turning the latter the paper ribbon is caused to feed up for a new line.- The main pressure-rolls being now released, the written bill may be pulled out and a fresh bill inserted'and gaged at the top of the platen. Thereupon the release-key '18 may berestored to normal posi- I .tion, thus bringing the pressure-rolls to the rolls into action when the main rolls are cast: off the rock-shaft 24 is provided with recesses 62, which are at right angles to the relcesses 25, so that when the shaft is rocked tibnary during the endwise movement of the shaft.

for separating the arms 26 27 it permits arms 6364, which are formed upon the arms 55 '56, to fall into the recesses, thereby per: mitting the springs 57 58 to press the arms 55. 56 and rolls 53 54 against the platen. Thus when either set of main or auxiliary rolls is released. the other set is brought into action.

When it is desired to have both the main and auxiliary rolls act in unison, as in feeding sheets which extend all the way along the platen, the releasing rock-shaft 24 may be moved endwise, being provided With end buttons 66 for this purpose and said shaft being 'sl uared at 67 to'fit asq'uare hole in the hub o the crankearm 23, the latter remaining sta- The arm may be otherwise splinedto the shaft. When the latter is moved to the Fig. 6 position, the arms 63 64fall-into recesses 25, so that at thisltime all of the rolls either release or'come into'action simultanel ously. It will thus be seen that two sets of cams are formed upon said rod, each ofthe recesses 25 consisting really of two recesses which merge into each other. The shaft may be detained in either of its endwise posi-- tions by means of a spring-tooth '69, which is adapted to engage annular depressions 70, formed in the shaft. v

' At Fig.9 a pulley 71 is mounted above the Windin -spool 51 to receive an endless band 72, WhlCh is of the same width as the pa er- 65 ribbon and runs between the latter an a sheet or strip 73, whereby two copies of the tally entries may be produced. It will be seen that a clear space is left between the bracket 48 and the paper-shelf 4 to permit insertion of wide sheets of paper, and it will be understood that said bracket may be detached, if desired, whenever it is necessary to use the machine for other purposes.
